Prime Minister Keir Starmer has declined to sack Mike Tapp, the Home Office Parliamentary Under-Secretary of State, despite an explicit request from Home Secretary Shabana Mahmood that he be removed for breaching the ministerial code.

Tapp, who was appointed to the role on 6 September 2025, wrote an unauthorised article in which he stated his "strong belief" that migrant care workers should not have to wait longer to apply for permanent settlement — a policy position that cut across the government's publicly stated immigration line. Mahmood, who holds departmental authority over immigration, asked Starmer to dismiss Tapp on the basis that the article constituted a ministerial code breach. Starmer's office has confirmed that Tapp remains in post.

The ministerial code requires ministers to clear public statements — particularly those touching on live policy — with their Secretary of State and, where applicable, with Downing Street. Writing for publication without that clearance is a textbook breach, and Mahmood's decision to escalate directly to the Prime Minister rather than manage it internally signals how seriously she regarded the infraction. The fact that Starmer did not act on the request is the more consequential development here.

Disputes between a Secretary of State and a junior minister are not unusual. What is unusual is a Prime Minister visibly siding with the junior. It creates an awkward structural position for Mahmood: her authority over departmental communications has been publicly qualified, and every future minister in her team now knows there is an appeal route that bypasses her. Whether Starmer's decision reflects confidence in Tapp, a deliberate recalibration of immigration messaging, or simply a judgment that dismissal would generate worse headlines than retention, the effect on departmental hierarchy is the same.

The substantive question Tapp raised — the settlement waiting period for migrant care workers — sits at an active fault line in government immigration policy. The care sector has relied heavily on overseas recruitment, and the Home Office's own enforcement data illustrates the scale of that dependency alongside its risks: between July 2024 and June 2025, 1,948 visa sponsor licences were revoked from employers found to be breaking the rules, more than double the figure for the preceding period. Tighter sponsorship enforcement and longer settlement pathways point in opposite directions for workers already in the country — and Tapp's article, authorised or not, named that tension plainly.

That context matters for reading the political dynamics. Mahmood has positioned herself as a firm hand on immigration compliance. Tapp's public statement complicated that positioning not merely procedurally but substantively, by signalling sympathy for a class of migrant workers at a moment when the government is emphasising rule enforcement. His retention suggests Starmer is not prepared to let enforcement messaging crowd out welfare considerations entirely — or at minimum, that he is unwilling to hand Mahmood uncontested control of how those trade-offs are communicated.

What happens next inside the Home Office will be worth watching. Mahmood's request was public enough that its rejection carries reputational weight. Junior ministers typically survive code breaches when the Prime Minister decides the political cost of dismissal is higher than the cost of retention; they do not typically survive a second one. Tapp, for his part, operates in a department where the Secretary of State has now formally put her position on record. That is not a comfortable working environment for either party, and it rarely stays static.
